'Shouldn't He Have More Important Things to Do?' How Jimmy Fallon Responded to President Trump's Twitter Insult

Jimmy Fallon has responded to President Donald Trump’s Twitter insult – by wondering aloud whether the Commander-in-Chief has better things to do than diss him online.

“When I saw that Trump insulted me on Twitter I was going to tweet back immediately, but I thought, ‘I have more important things to do,'” Fallon said in his Tonight Show monologue Monday. “Then I thought, ‘Wait, shouldn’t he have more important things to do?’ He’s the president of the – what are you doing? You’re the president. And you’re tweeting at me.”

Trump tweeted at Fallon Sunday night, describing the comedian as “whimpering” after he apologized for Trump’s infamous hair-mussing appearance on his show as a candidate in 2016. “Be a man Jimmy!” Trump wrote. Trump doubled down on his criticism of Fallon at a campaign-style speech in South Carolina Monday, calling the host “a lost soul” and “a poor guy,” according to USA Today.

.@jimmyfallon is now whimpering to all that he did the famous “hair show” with me (where he seriously messed up my hair), & that he would have now done it differently because it is said to have “humanized” me-he is taking heat. He called & said “monster ratings.” Be a man Jimmy!
